Bimetallic oxides are a class of
promising advanced functional
metal nanomaterials, especially in terms of the sophisticated hierarchical
structure of bimetallic oxide, which not only is in favor of enhancing
their intrinsic physiochemical properties because of more accessible
actives sites but also is capable of integrating the synergistic effect
between two metals. Herein, we report a novel strategy to controllably
construct bimetallic CuO/ZnO nanomaterials with sophisticated hierarchical
structure through a pseudomorphic transformation and subsequent calcination
process. The resulting unique hierarchical structure of ZnO/CuO is
primarily constituted of a nanosphere and a rod grafted in a microscale
cube with multidimensional size, which thus results in excellent dispersion,
superior charge-transport capability, and abundant accessible active
sites. Impressively, the optimized hierarchical structure product
of CuO/ZnO (4:1) demonstrates an excellent glucose detection performance
with a rapid response time, a wide linear range, a low detection limit,
and strong antiinterference ability, realizing more advantages than
commercial CuO or ZnO materials and shedding light on the positive
correlation of the structure and performance. This study provides
a new strategy for the controllable fabrication of the sophisticated
hierarchical structure of bimetallic oxide nanomaterials.
